Wikipedia has an interesting article on Australian demographics. You're pretty bang on with the numbers Mulchy, but numbers don't tell you everything. For example, English is the language spoken at home in only 80 % of households. That means that 20 % of Australians are bilingual. So cool. The section on Australian Culture is really interesting:

"Since 1788, the primary basis of Australian culture has been Anglo-Celtic, although distinctive Australian features soon arose from the country's unique environment and the pre-existing indigenous culture. Over the past 50 years, Australian culture has been strongly influenced by American popular culture (particularly television and cinema), large-scale immigration from non-English-speaking countries and Australia's Asian neighbours. Australian literature, cinema, opera, music, painting, theatre, dance, and crafts has achieved international recognition."

I don't know about tv, but I do know about art. You'll search hard to find a scene more diverse and multicultural than the Australian Art scene.

Think about your local shopping area, how many different types of cuisines there are. What about the local school? How many different nationalities are there in the kindergarten class?

Basically, I am trying to say, I don't ever expect to change your mind or point of view, but I would like to let you know that there are different ways of thinking about things. Australia is an incredibly diverse and fascinating country. Don't just dismiss it because of a "feeling", research, read everything and then think about what you like about the place.

They are SO awesome, I nearly died of excitement when I saw them, my sister once wrote a story about how one of them (the big bird one I think) was her pet. Still got the picture she drew somewhere, used to be obsessed with them.
